Seeing the massive amount of fraud and dishonesty in science, especially when it comes to getting material published, combined with the government’s track record of lying and incompetence, the simplest explanation for all of this is dishonesty or incompetence
The astonishingly solid track record of utter Buffoonery coming out of people who work in that building (leading to millions of people killed, maimed and tortured), spanning multiple decades -- might have something to do with it.
You believe they see some crap, jump to the conclusion it was "alien spaceships" and go on record declaring to have "working craft"?
I wonder who is who here.
